Unmalted barley is barley grain that has not undergone the malting process, which involves soaking, germinating, and drying the grain. This type of barley is often used in animal feed, as it retains its natural starches and nutrients. It can also be used in brewing and distilling, although it is less common than malted barley. In brewing, unmalted barley can contribute to the body and flavor of certain beers, particularly in styles like stout or porter. Additionally, it is sometimes used in the production of whiskey, where it can add unique characteristics to the final product.
